CRlMPlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 349,355, datedSeptember 21, 1886.

Application filed May T, 1886. Serial No. 201,495. (No model.)

To all whom it may concern.-

Be it known that I, FRANK It. PAOKHAM, a citizen of the United States,residing at Mechanicsburg, in the county of Oliampaign and State ofOhio, have invented certain new and useful Improvements inCrimping-Machines, of which the following is a specification.

This invention relates to that class of crimp ing-machines in which twocrimping-rolls mounted on separate bearings are adapted to intermesh andbe revolved to crimp the ends of pipe or other similar articles, toproduce a taper thereon.

The obj ects of the invention are, first, to provide a crimping-machinefor crimping pipe or other articles, and adapted to form an ogee grooveor head at the same operation which produces the crimping, the machinebeing capable of an adjustment whereby the ogee or heading rolls may bedispensed with without the necessity of supplying blanks to fill thespaces previously occupied thereby; second, to provide for crimpingshort flanges or projectionssuch as bucket-lids, &c.whereby theprojecting flanges or rims thereof may be formed 011 a taper when madefrom a straight piece of metal; third, to provide a novel arrangementfor adjusting the angle of the rolls, to produce a greater or less taperand vary the depth of the crimps; fourth, to provide for varying thedepth of the beading with reference to the crimping, whereby light orheavy bead-' ing may be produced with any desired length or depth ofcrimps, fifth, to improve the general construction of machines of thisclass, cheapenin g their construction, and at the same time adding tothe efficiency of their work. To this end my invention consists in thevarious constructions and combinations of parts hereinafter described,and pointed out in the claims.

I11 the accompanying drawings, Figure 1 is a side elevation view of amachine embodying my invention. Fig. 2.is a plan view of the swingingarm for supporting the upper roll, the ogee-roll being shown thereon indotted lines. Fig. 3 is a sectional elevation View of the frame, theupper supportingarm being removed. Figs. 4 to 8, inclusive, are detailedviews of some of the various'parts. Fig. 9 is a front elevation viewshowing the supplemental Shaft in the upper supporting-arm.

Fig. 10 is a side elevation view showing the machine adapted forcrimping short projections or flanges. Fig. 11 is a transverse sectionalelevation view on line X X in Fig. 10. Fig. 12 is a detailed view of thesupplemental shaft with the roll shown in section thereon. Fig. 13 is adetailed view of the auxiliary roll.

Like parts are indicated by similar letters of reference throughout theseveral views.

The main frame A consists, essentially, of the bearing B, at the bottomof which is aprojection, B, to fit the usual supporting-standard, and asingle upwardly-projecting side or wing, A. To the rear end of the wingor side A is pivoted .a supporting-arm, O, which is providedat the frontend with a sleeve or socket, 0, adapted to receive the shaft or hearingwhich supports the upper roll, D. The lower roll, D is supported on ashaft, D which extends through the bearing B of the main frame. Therolls D D are provided in the usual manner with a series of serrationsor flutes to produce the crimps, and are preferably made of the samediameter throughout. In order that the crimps may be produced of avarying depth, and thus form the crimped end of the pipe on a taper, theupper shaft or bearing is supported at an angle to the lower shaft, D.

It is sometimes desirable that the angle at which the rolls stand inrelation to each other he changed, so that the taper may be formed for agreater or less distance on the end of the pipe and a variation securedin the depth of the crimps. Itis desirable, however, that the rear endsof the rolls remain flush with each other. In order to provide for thisadjustment, I support the pivot a, on which the swinging arm 0 isjournaled, in a slotted open- 0 ing, a, formed inthe wing A on the arcof a circle struck from the intersection of the crimping-rolls at theirrear ends.

The pivot a. is preferably made in the form of a bolt, which passesthrough the slotted 5 opening a, and is provided at the outer end with anut adapted to screw thereon, a shoulder being preferably formed, sothat the bolt may be tightened in the side wing of the frame withoutbinding the supporting-arm thereon.

The socket or sleeve 0, in which the upper shaft, D is supported, is ofthe same diameter throughout, and is provided on one side with aset-screw, b, by means of which the shaft "f in the shaft D.

D" will be held in any desired position in said sleeve. On the upperpart of the wing A is a projectinglug, 0, through which projects the endof the usual hand-screw, c, the end of which is adapted to bear againstarm 0 to adjust the position of the upper roll, a coilspring, a,supported on the frame A, being adapted to support the weight of theupper roll and the swinging arm 0 and press said arm against the adjListing-screw c.

The upper shaft, D, is preferably passed through an arm, (I, provided atthe rear with a small projection, (7, adapted to engage in an opening, din the frame A. This lever d is provided with a hook, to which may beattached a chain or suitable connection leading to a foot-treadle, bywhich the position of the upper roll may be changed, thus dispensingwith the use of the hand-screw c.

E E are the ogee or beading rolls, which are usually employed inconnection with the crimping-rolls to produce a groove or head in thepipe being crimped. In order that these rolls may be dispensed with,when desired, without the necessity of supplying their place withblanks, as heretofore, i so construct and arrange the shaft D that itmay be readily moved longitudinally to take up the slack or space leftat the end thereof when the beading-roll is removed. To do this Iconstruct the shaft of the same diameter throughout, and provide meansfor securing the shaft against longitudi nal motion in the differentpositions of adjustment, which means permit the shaft to be revolved ineither position of adj ustment. The shaft is also provided at theforward end with suitable means for connecting the rolls thereto, sothat said rolls will revolve therewith, but in such a manner that theshaftmay be moved longitudinally in relation thereto. This I preferablyaccomplish by providing in the forward end of the shaft 1) a keyway, c,with which a suitable spline or projection, e c'-', on the rcspectiverolls is adapted to engage.

At the rear end of the frame A is provided a hinged latch, f, adapted toengage in grooves The rolls are held 011 the end of their respectiveshafts by means of nuts F F. These nuts are preferably screwed into theend of the shaft and are provided in the center with a suitable opening,{1, adapted to receive the end of a square key or wrench, by which theymay be screwed into or out of their respective shafts.

\Vhen it is desired to use the machine without the ogec or head rolls,the nuts F F are withdrawn and the ogee-rolls removed. The latch f israised from the groove 1'' and the shaft I) slipped back until in theposition shown in Fig. 3 the latch f is dropped into groove f, Theset-screw b in the upper supportingarm, 0, is loosened and the shaft (1is slipped back through the sleeve 0 until the space oeoupied by theroll E is taken up. The nuts F F are then replaced and the machine isready for operation without the ogee-rolls.

The nuts F F, I preferably make with a very thin head, which, ifdesired, may be countersunk in the end of the roll. in this way when theogeerolls are removed the ends of the crimping-rolls are leftunineumbercd, so that they may be employed for crimping shortprojections or fiangcssuch as the projections of bucket-lids, 850.

It is sometimes desirable, especially when crimping stove-pipe of poorquality, thata variation be effected in the beading formed thereinwithout varying the crimps or taper of the end of the pipe. For thispurpose I provide a supplemental shaft, D", adapted. to fit into thesleeve 0 of the supporting-arm C. This shaft D is provided at theforward end with a cam, D on which the ogce-roll is journaled, thecrimping-roll beingjournaled on the main part of the shaft in the usualmanner.

The end of the shaft 1) is provided with a socket, adapted to receivethe end of a suitable key or wrench, by means of which the shaft may beturned to any desired position.

XV hen it is desired to effect a variation in the groove or bead withoutchanging the crimp produced in the pipe, the shaft D is removed from thesleeve and the shaft 1) substituted therefor.

It will be seen that by turning the shaft D in the hearing or sleeve 0the ogee-roll may be broughtinto any desired position with relation tothe lower roll. The crimping-roll being journaled on the main portion ofthe shaft, whose centeris on a line with the center ofthc sleeve C, novariation is produced therein by the revolution of theshaft l). Theogee-roll, however, being journaled on the cocentric portion D of theshaft, maybe placed in any desired position with reference to the lowerroll by simply turningthe said shaft in its bearings. The eccentric ispreferably formed so that, if desired, the ogee-roll may be raisedsufficiently so that it will be entirely withheld from contact with thework.

In order that the swinging arm 0 may beheld firmly against lateralmotion, and at the same time be permitted to rise or fall in :uljustmentof the ei-impingrolls, 1 provide on the side thereof a projection, ll,near the front end, adapted to pass through a slotted opening, h, in theside or wing of the frame A, a washer, h", being provided thereon on theoutside of the said wing, as shown in Fig. 11.

The side of the arm 0 next to the wing A. is faced off to form abearingagainst the said wing. By this construct-ion thearm isadapted to movefreely up and down upon its pivotal bearing a, but is held againstlateral motion thereon.

In Figs. 10 and 13 I have shown crimpingrolls adapted expressly forcrimping short projections or flanges, such as the projections or rimsof bucket-lids or similar constriurtions. These rolls 1) D are eachprovided with an extended sleeve or collar adapted to take up the spaceon the respective shafts D and D occupied by the cri mping-rolls andogee-rolls. The lower roll is provided with a suitable projectionadapted to engage in the keyway in shaft D, the said rolls being ofsufficient length to stand flush with their respective shafts on thesaid journals.

When it is desired to crimp a projection close up to a shoulder orcorner, the nuts F F may be dispensed with, the pressure of the workagainst the rolls being sufficient to hold them in place.

It will. be seen that by the construction above described I provide amachine capable of ready adjustment for any kind of work. The frame,being formed with a single wing or side projection, may be readily castwith the slotted openings therein without the use of cores.

By the construction of the hinged supp ortingarm 0 above described inconnection with the frame A, it will be seen that the bearing for theupper roll, D, is independent of the swinging arm, and may be readilyremoved and replaced as desired. By this construction the labor infitting up the machine is materially decreased. The lower shaft, D,being of the same size throughout, may be formed from cold-rolledshafting with very slight fitting thereon. All the parts are exceedinglysimple, and may be readily constructed and assembled with very littlefitting, except such as may be accomplished by ordinary straightforwardmachinework.

It is obvious that the constructions may be considerably varied, ifdesired. Instead of the latch f, asuitable sliding pin or key might beused with equally good results.

If desired, several grooves might be employed in the main shaft toprovide for different-sized rolls or different adjustments of themachine.

The lever d or the hand-screw c 1nay either be employed to the exclusionof the other, or both may be used, as desired.

Other modifications may be em ployed,which will readily suggestthemselves to the mind of an ordinary mechanic.
